TECHNICAL FIELD

Embodiments of the present disclosure relate to a medical dataprocessing method, a medical data cluster processing system, and amedical data cluster processing method.

BACKGROUND

Currently, processing of medical data mainly depends on somehigh-performance devices with specific purposes, such as a high-enddevice with high computing power. However, such a high-end device is notusually equipped in general hospitals. For grassroots medical clinics,or in some remote areas, a medical device with high computingperformance is often unavailable. Moreover, these high-end devices areoften disposed in fixed positions, and are difficult for the generalpatients to access.

In addition, with the development of data processing technology, moreeffective medical data algorithms continue to emerge. However, thesealgorithms require higher computation amount, and for a home portablemedical device, it is difficult to run these algorithms on the homeportable medical device. Currently, in order to calculate a large amountof complex medical data, one approach is to upload the data to a medicaldata center through the network for processing, and then download aresult to a local end. But this approach may lead to a problem ofprivacy leakage of patient data. Another approach is to enhance theprocessing power of the local hardware. However, this approach isunrealistic for the grassroots medical clinics or in some remote areas.For a general medical device, enhancement of the local computing powerwill greatly increase the cost of the device, and frequency of using theenhanced local computing power in the whole life cycle of the device isnot high, which will cause the waste of resources.

In the following, the preferred embodiments of the present disclosurewill be described in detail with reference to the drawings. It should benoted that, in the specification and the drawings, a same label in thedrawings represents to a basically identical step and element, and therepeated explanations of the identical steps and elements will beomitted.

In the following embodiments of the present disclosure, a firstelectronic device and a second electronic device are devices that arecapable of communicating with other devices. Specific forms of the firstelectronic device and the second electronic comprise, but are notlimited to, mobile terminals, personal computers, digital cameras,personal digital assistants, portable computers, etc. The electronicdevices may also be terminal devices or server devices.

FIG. 1 shows an exemplary architecture diagram 100 of a network modelaccording to an embodiment of the present disclosure. Referring to FIG.1, in the network model of an embodiment of the present disclosure, afirst electronic device 110, for example, is a device that initiates anelectronic device cluster and controls the operation of the cluster, andthe first electronic device 110 is referred to as an initiator devicefor convenience. A second electronic device 120, for example, is adevice that responds to a broadcast message of the initiator device andparticipates in the cluster, and the second electronic device 120 isreferred to as a participant device for convenience. In the networkmodel, the network model may comprise only one first electronic device110 and at least two second electronic devices 120. For example, in FIG.1, the network model comprises eight second electronic devices 120.Based on the broadcast message of the initiator device, the initiatordevice and all of the participant devices may form a computer cluster atanytime and anywhere. The initiator device establishes and controls thecluster, the participant devices process medical data according to aninstruction of the initiator device and communicates information withthe initiator device. The structure and function of the initiator deviceand the participant devices are described respectively below.

Firstly, a medical data acquisition method implemented by the initiatordevice is introduced. FIG. 2 shows an exemplary flow chart 200 of amedical data acquisition method according to an embodiment of thepresent disclosure, and the medical data acquisition method of anembodiment of the present disclosure will be described below withreference to FIG. 2.

Referring to FIG. 2, in the step S201: sending model data and medicaldata to at least two second electronic devices, the second electronicdevices being communicatively connected with the first electronicdevice. For example, the model data may be processing model data usedfor processing the medical data, such as a processing algorithm, aprocessing model, a processing tool and the like. The model data mayalso be an analysis model random forest, and the random forest includesa plurality of irrelevant decision trees. The medical data may bemedical data, such as a medical image, medical statistics data and thelike. As described above, the first electronic device may be a clusterinitiator device. The second electronic devices each may be a clusterparticipant device. The first electronic device and the secondelectronic devices may be communicated with each other through thenetwork. In a case that the initiator device initiates a clusterestablishment instruction through the network, after a participantdevice receives the cluster establishment instruction through thenetwork, the participant device has a signal connection with theinitiator device through the network, so as to participate in thecluster established by the initiator device. The cluster comprises theinitiator device and at least two participant devices. Certainly, aperson having ordinary skill in the art can understand that although inthe present disclosure, a medical processing model processes the medicaldata, which is taken as an example to describe the medical dataacquisition method, but the medical data acquisition method may also beapplied to other technical fields. For example, an industrial processingmodel is used to process industrial data, a military processing model isused to process military data, etc.

After the cluster is established, the initiator device may send themodel data and the medical data to at least two participant devices inthe cluster. For example, in a case that a first electronic device needsto process complex medical data, the first electronic device mayinitiate a cluster establishment notification through the network, so asto request other electronic devices to process the medical datatogether. After two second electronic devices participate in thecluster, the first electronic device, as the initiator device, may sendthe medical data that needs to be processed and the processing modeldata of the medical data to respective second electronic devicesrespectively, so as to request respective second electronic devices toprocess the medical data together in parallel, and thus the processingability and efficiency of the medical data is improved.

In the step S202: receiving multiple pieces of second processing datasent from the at least two second electronic devices. The secondprocessing data is processing data obtained by processing the medicaldata based on the model data by the second electronic devices.

In a case that each second electronic device receives the model data andthe medical data from the first electronic device, each secondelectronic device processes the medical data to obtain a correspondingpiece of second processing data, and sends the piece of secondprocessing data to the first electronic device. The first electronicdevice receives multiple pieces of second processing data. For example,a processing module used as the model data, analyzes a medical imageused as the medical data. For example, a disease position in a pair or apiece of the medical images is analyzed and identified to obtain ananalysis result. In order to ensure security of the data, the firstelectronic device may encrypt the model data and the medical data andthen send the encrypted model data and medical data to at least twosecond electronic devices, and the first electronic device receives thecorresponding second processing data encrypted and sent from respectivesecond electronic devices.

In the step S203: comprehensively processing the multiple pieces ofsecond processing data received from at least two second electronicdevices to obtain a medical data processing result.

According to an embodiment of the present disclosure, the model datacomprises a first sub data set including multiple pieces of first subdata. The initiator device respectively sends the first sub data set asa whole to each of the at least two second electronic devices. Eachparticipant device processes the medical data based on all the first subdata in the first sub data set to obtain the corresponding secondprocessing data, and sends the corresponding second processing data tothe initiator device. For example, the processing model data used as themodel data comprises a plurality of processing modules, each processingmodule acts as one first sub data, and all of the processing modulesform the first sub data set. The initiator device may send the pluralityof processing modules included in the processing model data to eachparticipant device, each participant device processes the medical dataaccording to the processing model data formed by the plurality ofprocessing modules and sends the result to the initiator device. In thisway, the initiator device may comprehensively process to obtain themedical data of the third data according to the processing data returnedby each participant device. A comprehensive processing approachmentioned above, for example, may comprise performing statisticalanalysis on all data, determining a maximum, minimum or average value,and so on. For example, analysis results of each participant device onthe disease are combined together to evaluate the diseasecomprehensively.

According to an embodiment of the present disclosure, the model datacomprises a first sub data set including multiple pieces of first subdata. The initiator device may also send a part of the data in the firstsub data set to one of the at least two second electronic devices, andsend the other parts of the data in the first sub data set to the othersof the at least two second electronic devices respectively. For example,the processing model data comprises a plurality of processing modules,each processing module acts as one piece of first sub data, and allprocessing modules form the first sub data set. Also for example, themodel data is an analysis model random forest, with a plurality ofirrelevant decision trees of the analysis model random forest beingdivided into a plurality of groups, and the plurality of groups isassigned to different participant devices. The initiator device maydivide the plurality of processing modules included in the processingmodel data into multiple parts according to the number of theparticipant devices, and sends different parts to different initiatordevices respectively. Each participant device processes the medical dataaccording to the received one or more groups of processing modules ordecision trees, and sends the result to the initiator device. In thisway, in a case that the medical data is complex and the data processingmodel is also very large, the initiator may instruct each participantdevice to process the medical data according to a part of processingmodules, and combine the processing results returned by each participantdevice to obtain a final medical data processing result. For example,the initiator device needs to analyze the medical data in differentways, and therefore the data processing model comprises a first analysismodule, a second analysis module, . . . , and an Nth analysis module. Inorder to improve computing efficiency, the initiator device may dividethe first analysis module, the second analysis module, . . . , and theNth analysis module into several parts, and assign the several parts toa plurality of participant devices. The initiator device receives andcombines the analysis results of respective participant devices, so asto improve the processing efficiency of the complex medical data.

According to an embodiment of the present disclosure, when the initiatordevice assigns the processing modules of the data processing model, theprocessing performance parameters of the participant device may beconsidered to set allocation rules. For example, the processingperformance parameters can be obtained from the participant device, andbased on the processing performance parameters of the participantdevice, the processing module(s) of the data processing model sent tothe participant device is determined. For example, the initiator deviceobtains information of the participant devices, such as a processingspeed of a processor, a storage capacity of a memory and so on, from theparticipant devices. The initiator device sends a processing module witha large amount of computation to a participant device with a highprocessing speed, and sends a processing module that generates a largeamount of data to a participant device with a large storage capacity. Bybalancing the performance parameters of the participant devices, theadvantages of each participant device may be utilized, so as to furtherimprove the parallel processing capability of the cluster.

According to an embodiment of the present disclosure, in a case thatpart of the first sub data in the first sub data set is related to eachother, for example, the first sub data and the second sub data arerelated to each other. The initiator device may send the first sub dataand the second sub data which are related to each other to one secondelectronic device based on the relationship between the first sub data.For example, in a case that the data processing model comprises thefirst analysis module, the second analysis module and other processingmodules; if the second analysis module is an analysis module based on ananalysis result of the first analysis module, then the initiator devicemay send the first analysis module and the second analysis module to oneparticipant device, and receive corresponding second processing dataanalyzed based on the first analysis module and the second analysismodule from the participant device, so that a data transmission timebetween the initiator device and the plurality of participant devices issaved.

Certainly, the present disclosure is not limited thereto. According toanother embodiment of the present disclosure, in a case that the firstsub data and the second sub data in the first sub data set are relatedto each other, the initiator device may also send part of the first subdata related to each other to one second electronic device, and send theother part of the first sub data to other second electronic devices. Forexample, in a case that the data processing model comprises the firstanalysis module, the second analysis module and other processingmodules; if the second analysis module is an analysis module based on ananalysis result of the first analysis module, then the initiator devicemay also send the first analysis module to a participant device A andsend the second analysis module to a participant device B. Under thiscircumstance, the participant device B may process the medical data byadopting other ways. For example, based on a first analysis result inprevious historical data, the second analysis module may be used toanalyze the first analysis result in the historical data to obtain anapproximate analysis result. Or, based on the first analysis module inthe historical data and the received second analysis module, the medicaldata is processed.

According to an embodiment of the present disclosure, the initiatordevice may also use the participant device to optimize the processingdata model. After the participant device sends the processed secondprocessing data to the initiator device, the initiator device maycorrect the second processing data and send correction data, e.g., thesecond processing data after being corrected, to the participant deviceagain. The participant device obtains optimization parameters of theprocessing module(s) in the processing model data based on the receivedcorrection data.

In addition, according to an embodiment of the present disclosure, afterthe participant device sends the processed second processing data to theinitiator device, in addition to correcting the second processing data,the initiator device may also update the data, such as adding new data,and send the corrected and updated data to the participant device again.The participant device obtains the optimization parameters of theprocessing module(s) in the processing model data based on the correctedand updated data being received.

In order to improve the parallelization of data processing, theinitiator device may assign the processing modules with a processingsequence relationship in the processing data model to differentparticipant devices, so that all participant devices may process themedical data in parallel compulsorily. In order to ensure the accuracyof the data, the initiator device may correct the processing resultcalculated by each participant device. The way in which the initiatordevice corrects the data, for example, may be a way in which theprocessing result is corrected by using known data, threshold data or anexpected value.

According to an embodiment of the present disclosure, the initiatordevice may determine an initial weight of each first sub data in thefirst sub data set. When sending first sub data in the first sub dataset to the participant device, the initial weight(s) of thecorresponding first sub data is sent to the participant devicesimultaneously. In this way, when the second processing data receivedfrom at least two participant devices are combined, the initiator devicemay comprehensively process the multiple pieces of second processingdata received from the at least two second electronic devices based onthe initial weight(s) of the first sub data to obtain the third data.For example, in a case that the data processing model comprises aplurality of processing algorithms and each processing algorithm has adifferent initial weight based on the accuracy or effectiveness of thealgorithm, the initiator device may obtain the final medical analysisresult by multiplying the processing results received from theparticipant device by the corresponding weights.

According to an embodiment of the present disclosure, the participantdevice may process the processing model data sent by the initiatordevice, such as changing or correcting the processing model data. Forexample, after receiving the data processing model from the initiatordevice, the participant device determines whether the data processingmodel needs to be changed or not; in a case that the data processingmodel needs to be changed, the participant device changes the dataprocessing model correspondingly. For example, in a case that the dataprocessing model received from the initiator device comprises aplurality of processing modules and each processing module has aninitial weight, under this circumstance, the participant devicedetermines whether the initial weight of each received processing moduleneeds to be changed or not according to the historical data thereof. Ina case that the initial weight needs to be changed, the initial weightis modified to a second weight, and the second weight is returned to theinitiator device subsequently. For example, in a case that thehistorical data shows that the initial weight received does not matchwith the corresponding processing module, it is determined that theinitial weight needs to be changed, and then the participant device maychange the initial weight correspondingly. The initiator devicecomprehensively evaluates the second processing data according to thesecond weight(s) to obtain the final medical analysis result. Certainly,the participant device changing the weight is just an example, and aperson having ordinary skill in the art can understand that theparticipant device may also change other properties of the dataprocessing model and the medical data received from the initiator deviceaccording to requirements. For example, the other properties comprise aversion and content of the data processing model, a format and contentof the medical data and so on.

According to an embodiment of the present disclosure, the medical datamay comprise a second sub data set including multiple pieces of secondsub data. The initiator device may send a first part of the second subdata in the second sub data set to one of the at least two secondelectronic devices, and send a second part of the second sub data in thesecond sub data set to the other(s) of the at least two secondelectronic devices respectively. For example, the medical data is amedical image, and the initiator device needs to recognize the medicalimage to determine whether the medical image has a lesion area. In orderto improve the recognition efficiency, the initiator device may dividethe medical image into a plurality of blocks, send one or more of theplurality of blocks to one participant device, and send the other blocksto other participant devices. Each participant device recognizes itsreceived image block(s), and sends a recognition result to the initiatordevice. After the initiator device receives a corresponding recognitionresult of the recognized image block(s) sent from each participantdevice, the initiator device combines the recognition results to obtainthe desired medical data. For example, after combining the recognitionresults, it can be determined whether the whole medical image has thelesion area, where the lesion area is located and so on. For example,each participant device scores each pixel in the image that is processedby itself to determine whether the pixel is the lesion area or not;after the initiator device receives the processing result, the initiatordevice may add the score of each participant device together todetermine whether a sum of the scores exceeds to a preset threshold ornot, so as to determine a location and size of the lesion area.

According to an example of the present disclosure, in order to ensurethe safety of the medical data and protect the privacy of the patients,a safety processing virtual area may be disposed in part or all of theparticipant devices. The safety processing virtual area is safelyisolated from the other areas of the participant device. The participantdevice stores the data processing model and the medical data receivedfrom the initiator device in the safety processing virtual area. And,the participant device processes the medical data based on the modeldata in the safety processing virtual area to obtain the secondprocessing data. For example, the initiator device is provided with asandbox mechanism; except that the initiator device may control thesafety processing virtual area of the participant device and theprocessing operation in the safety processing virtual area, the otherdevices or components may not access and control the safety processingvirtual area of the participant device. For example, even users of theparticipant device itself can not control the data processing in thesafety processing virtual area, so as to ensure the closure of the wholeprocess and the privacy of patient data. In addition, even if the datareceived from the initiator device contains a virus program, because alldata received from the initiator device is stored in the safetyprocessing virtual area and is processed isolatedly, other devices andcomponents of the participant device are not affected by the virusprogram, and the safety of the participant device is ensured.

Through establishing a computer cluster, the present disclosure providesthe feasibility of computing the complex medical data in parallel byexisting general devices. Because the cluster may be established atanytime and anywhere, the flexibility of data processing is improved.Moreover, because the data is processed in the safety processing virtualarea, so as to effectively protect the privacy of the patient data.

According to an embodiment of the present disclosure, a medical dataprocessing method is provided, and the medical data processing method isapplied to a participant device in a cluster, namely the medical dataprocessing method is applied to a process that a cluster participantresponses to an instruction of a cluster initiator to process themedical data. In the above description of operations performed by theinitiator device in the cluster, operations performed by the clusterparticipant device has been described in details, and for the simplicityof the specification, a brief introduction will be given in thefollowing, and the details may be referred to in the above embodiments.
